Is a 42inch aero marine Sprint cat worth building. I did some digging on the forum and found two builds one with a neu 1527 1y and one with a castle 780kv motor . They both seem rather slow from my readings . Is it even possible to get this hull to the 70s while running as an electric. So is it honestly worth building a large but potentially slow boat. If it is worth it what could I possibly use to get this hull to put up some breath taking performance.
